Teenage Mutant Ninja Turtles: Shredder's Revenge is a great package. The lives system is forgiving but not so forgiving where you can breeze through the game which is a great balance in difficulty. I wish the level progression carried over between characters so I could freely swap between them but with the game's short length, I can understand why this isn't the case. The presentation is top notch with great sprite work and great animations. Gameplay is you're typical beat-em-up that only gets annoying when the introduce any flying enemies, as there aren't a lot of options for dealing with midair foes besides a flimsy air kick. Overall it's challenging but fair and nicely short so you can beat it in a session or two.
